PAPER-PLAITING MACHINE.

Application filed September 6, 1913.

To all whom it may concern Be it known that I, PHILIP F. COHEN, a citizen of the United States of America, residing at New York city, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Paper-Plaiting Machines, of which the following is a full, clear, and exact description.

This invention relates to an improved paper-plaiting machine, the function of which is to plait or crimp paper which is afterward used for wrapping boxes of candy.

My improved machine is designed to plait or crimp a strip of paper as it comes from a roll and to cut the same, after plaiting, into the desired lengths for wrapping.

My improved machine is designed to take the place of hand work both as to speed and effectiveness, and is a simple and inexpensive structure, for the purpose intended.

I will now proceed to describe my invention in detail, the novel features of which will be pointed out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is a top plan view of an embodiment of my invention; Fig. 2 is a side elevation thereof; Fig. 3 is an enlarged cross section, taken on a line 33 in Fig. 1; Fig. 4 is an enlarged cross section, taken on a line 44 in 1 Fig. 5 is an enlarged crosssection, taken on a line 5-5 in Fig. 1; F ig; dis a fragmentary longitudinal view, taken on a line 66 in Fig. 5; Fig. 7 is an enlarged cross-section taken on a line 77 in Fig. 1; Fig. 8 is a fragmentary longitudinal sectional view taken on a line 8-8 in Fig. 7; Fig. 9 is an enlarged cross-section, taken on a line 9-9 in Fig. 1; Fig. 10 is a cross-sectional view taken on a line 10-1O in Fig. 9; Fig. 11 is a diagrammatic view of a section of the paper when completely plaited; Fig. 12 is a side elevation of another form of plaiting block which may be used in my machine; Fig. 13 is an enlarged cross section thereof, the section being taken on line 13-13, Fig. 12; and Fig, 14 is a similar view, taken on line 1414, Fig. 12.

As herein constructed, my improved plaiting machine comprises a table or bed 1, upon which is mounted, from left to right, a paper-roll support 2, a curved framing device 3, a plaiting mechanism 4, a straight or flat framing device 5, a feeding device 6, a cut- Speeification of Letters Patent.

ting device 7 and a take-up 8. A portion of the plaiting device 4 consists (in this in stance) of a plurality of blocks or formers 9 and 10 which are fixed in the operation of the-machine, but are adjustable transversely of the bed 1 (see Fig. 3). Each former 9 and 10 is provided with a threaded lug 11. Through the threaded opening of each lu a threaded spindle 12 passes, said spindle Feing provided with a right and left hand thread engaging similar threads in the lugs 11. The formers 9 and 10 travel in a guideway 13 in the bed 1. The spindle 12 is rotated by means of a hand-wheel 14*. Each of these blocks or formers extends longitudinally of the machine and in line with the travel of the material to be acted on, and is provided in its outer side with longitudinal grooves, channels or continuous recesses 15 in different horizontal planes.

These formers collectively constitute a form-.

ing device arched transversely, elongated longitudinally of the machine and grooved as above stated in its sides, which are of course the outer sides of its two constituent formers. Further elements of the plaiting device, consist of a plurality of rollers 14 formed to take into the channels 15 of the formers 9 and 10. I have herein illustrated six rollers 14, but more or less may be used if desirable. Each roller 14 is carried at one end of an arm 16 pivoted as at 17 to the bed 1. Springs 18 keep the rollers 14 in position in the channels 15 of the formers 9 and 10. While the formers 9 and 10 are herein illustrated as being provided with three channels each, more or less may be used, according to the number of plaits desired in the wrappers.

' The function of the curved framer 3 is to curve the paper 00 as it leaves the roll 19 and thus prepare it to enter between the rollers 14 and formers 9 and 10, by causing it to assume a shape that will partly envelop the formers therefor; the rollers will press the paper 00 into the channels 15 and crimp same (see dotted lines 20, Fig. 3). Each of these rollers on each side of the forming device is in a different transverse plane, as well as in a different horizontal plane, from those of the other rollers on said side, that the strain may be distributed to the best advantage.

The arched framing device 3 consists of a plurality of separable sections 21 and 22 (see Fig. 7), mounted upon blocks23, 23 carryed spindle 25 passes. The spindle 25 is pro- .vided with a right and left-hand thread engaging similar threads in the lugs 24. One end of the spindle 25 carries a sprocket gear 26 (Fig. 1) which, by means of a chain 27, is driven by a sprocket gear 28 (Fig. 1) on the. spindle 12 of the forming blocks 9 and 10. The framing members 21 and 22 provide between them a channel or guideway 29 whichis arched transversely of the line of travel of thematerial. This channel eX- tends longitudinally of said line and will permit the paper to pass therethrough.

The straightening framer 5 consists of the separable members 30 and 31 (Fig. 5) carriedby blocks 32, 32 having threaded lugs 33 through which a spindle 34 having a right and left-hand thread passes. The blocks 32 travel in a guide 35 in the bed 1. The blocks 23 of the curved framers 21 and 22 travel in a guide 36 in said bed 1. The outer end of the spindle 34 carries a sprocketgear 37 which by. means of a chain 38 is driven by a sprocket-gear 39 on the spindle 12 for the formers 9 and 10. The function of the framer 5 is to straighten the plaited paper, or rather flatten it, to prepare it to enter the feeding device 6.

The feeding device 6 (Fig. 4) consists of rollers 40 and 41 mounted in standards 42- and 43. The roller 40 is rotatably mounted in boxes 44 slidably mounted in guides 45 in the standards. Pressure screws 46 keep the rollers 40 and 41 incontact. One end of each shaft 47 and 48 for the rollers carries a gear 49 which mesh one with the other. The opposite end of the shaft 48 is provided with a sprocket-gear 50 and adjacent there: to is mounted a second sprocket-gear 51. The take-up 8 is identical with the feeding device 6. The lower shaft 52 of the take-up device is provided with a gear 53. The function of the take-up device is to keep the paper taut. to facilitate the cutting thereof by the cutting device 7. The sprocket-gears 51 and 53 are connected by a chain 54; hence the feeding device and take-up operate in unison.

As can be seen in Fig. 1, the cutting device 7 is positioned intermediate the feeding device and take-up.

By referring to Fig. 9, it will be seen that the cutting device 7consists of a cutting roll 55 and a die-roll 56. The rolls and 56 are carried by shafts 57 and 58, respectively, which in turn are mounted in standards 59 and 60. The shafts 57 and 58 are each provided at one end thereof, with intermeshing gears 61. The free end of the shaft 58 is adapted to removably support a sprocketgear 62 which is connected to the sprocketgear 50 by a chain 63 (Fig. 1). The cutting device operates in unison with the feeding device 6, provided the gears 50 and 62 are of the same diameter. To change the speed of the cutting device relative to the feed of the feeding device, I change the sprockets 50 and 62. Should the sprockets 50 and 62 be of the same diameter, the paper would be cut in lengths equal to the circumference of the feed rollers 40 and 41, which I will suppose is twelve inches; consequently the paper will be cut in one foot lengths. To

- out the paper in six inch lengths, the sprockets 50 and 62 would be two to one, sprocket 50 being the larger. 'To obtain different lengths of wrappers, it will be seen that. I have but to change the sprockets 50 and 62. It will be evident that I can simultaneously adjust the framers 5 and 7 and plaiting distribute the strain upon thepaper, as the pressure upon the paper will not be applied i to a restricted locality; therefore the paper 5 will not be so liable to tear. A motor 64 may be used to actuate t is feeding device, cutter and take-up.

In Figs. 12, 13 and 14, I have illustrated another form of plaiting block or former, consisting of the members 65 and 66 provided with channels 67. Fig. 12 it; will be seen that the channels 67 By referring to are considerably wider at the end 68 of the block than at the end 69, and it will also be seen that the said channels are placed at an angle or inclined relative to the top surface of the block. The object of forming the blocks in this manner is to provide for the gradual plaiting of the paper, to prevent tearing thereof, as the channels at that end of the blocks which the paper is fed on are sufliciently wide to produce an'easy creasing of the paper, and as the said crease is fed toward the opposite end of the block the channels gradually decrease in width. The gradual decreasing of the width of the channels permits the material to be gradually plaited. With this form of block I may employ rollers 14 located adjacent each end of the block and centrally thereof, in order to gradually form the plaits.

Having now described my invention, what I claim and desire to secure by Letters Patent is: e
